You can easily and cheaply buy sensors that can measure a variety of variables that would be interesting in industrial applications, for example (and this is for sure not a complete list): light or sound intensity; voltage; current; pressure; temperature; rotational position; XYZ orientation; compass direction; acceleration; location; fluid flow rate and so on.
These sensors can be interrogated by microcontroller, and data stored to memory card, or communicated in realtime to other systems via Bluetooth, Zigbee, WiFi , Ethernet, serial, USB, infared and so on.
The inexpensive nature of these microcontrollers (for example Google for ESP8266 to see a WiFi-enabled microcontroller) means that you could deploy a large number of these in an industrial setting (even in hazardous environments) and gather data without a large capital investment, and without the worry of “what if it gets destroyed”.
There must be so many industrial applications of this technology that it’s impossible to enumerate the possibilities. The limiting factor is really only “how can we process all of this data”.
he Industrial IoT focuses strongly on intelligent cyber-physical systems. These systems comprise machines connected to computers that interpret, analyze and make decisions almost instantly, based on sensor data from many widely distributed sources.
The Industrial IoT enables the smart system in your car that brakes automatically when it detects an obstacle in the road. It enables the patient monitoring system in hospitals to track everything from a patient’s heart rate to their medication intake. It enables a mining machine or space robot to safely and efficiently operate where humans can’t.
The world is building more and more intelligent machines that interact with other machines, with their environments, with data centers and with humans.
Counted as the most mature wireless radio technology, Wi-Fi is predominant communication technology chosen for IoT applications. Already existing protocols like WPS make the integration of internet of things devices easier with the existing network. If we talk about transmission then Wi-Fi offers the best power-per-bit efficiency. However power consumption when devices are dormant is much higher with conventional Wi-Fi designs. The solution is provided by protocols like BLE and ZigBee that reduce power consumption by sensors when devices are dormant.
Most important use of Wi-Fi is in the applications where IP stack compliance is needed and there is high data transmission. For instance in applications sharing audio, video or remote device controlling.
As the prerequisites of internet of things are scaling up, companies are working on more integrated solutions. But even at present there are many solutions available for anyone who is trying to build up internet of things applications around the major three IoT components. Vendors
ZigBee is a low power consuming IEEE 802.15.4(2003) standard based specification, ZigBee is a brain child of 16 automation companies. What makes it novel is the use of mesh networking which makes utilization of communication resources much more efficient. ZigBee based IoT nodes can connect to central controller making use of in-between nodes for propagating the data. It makes transmission and handling of data robust.
Integration of IoT technologies into manufacturing and supply chain logistics is predicted to have a transformative effect on the sector. The biggest impact may be realized in optimization of operations, making manufacturing processes more efficient. Efficiencies can be achieved by connecting components of factories to optimize production, but also by connecting components of inventory and shipping for supply chain optimization.
Another application is predictive maintenance, which uses sensors to monitor machinery and factory infrastructure for damage. Resulting data can enable maintenance crews to replace parts before potentially dangerous and/or costly malfunctions occur.
No. The Internet of Everything does not describe a specific architecture and is not solely owned by Cisco or IBM or any other company.
It already is having an impact. A recent report from Gartner says there will be 4.9bn connected things in 2015, rising to 25bn by 2020. What are these things, though?
“Let us not focus on fridges,” says Will Franks, who sold Ubiquisys to Cisco for ?204m in 2013. Franks, who has just helped set up the Wireless IoT Forum, lists a number of consumer touch points. “Keeping track of possessions where insurance companies could reduce premiums,” he says. “Home control devices, maintenance checks for cars and white goods, healthcare and so on.”
He doesn?t mention robots or Facebook. Robots will be connected too in a smart home of the future, at least according to the GSMA. And Facebook? According to The Register, it?s planning to launch software development kits (SDKs) for IoT apps and devices. Heating control through systems such as Nest and Hive are just the start, it seems.
Wireless sensor network is the foundation of IoT applications.
WSN is the network of motes, formed to observe, to study or to monitor physical parameters of desired application.
For example – Motes deployed in Agriculture land, monitor Temp-Humidity or even soil moisture, who gathers data and with perfect data analysis produce results about crop yields – quality or quantity.
IoT is the network of physical objects controlled and monitored over internet.
Now just as WSN, in IoT application you will encounter the monitoring of physical parameters. But desired outcomes are little different.
IoT is more about M2M, it is more about bringing smartness into daily objects.
For example – Device hooked to your Thermostat monitors surrounding temperature and adjust it to most preferred setting for
To put things simply any object that can be connected will be connected by the IoT. This might not make sense for you on the forefront but it is of high value. With interconnected devices you can better arrange your life and be more productive, safer, smarter and informed than ever before.
For instance how easy it will be for you to start your day if your alarm clock is not only able to wake you up but also able to communicate with your brewer to inform it that you are awake at the same time notifies your geezer to start water heating. Or you wearable wrist health band keeps track of your vitals to inform you when you are most productive during the day. These are just few examples but applications of internet of things are numerous.
On large scale transportation, healthcare, defense, environment monitoring, manufacturing and every other field you can imagine of can be benefited from IoT. It is very hard to conceive the whole application domain of internet of things at the moment but you can clearly understand why it is such an interesting and hot topic at the moment.
Given that smart objects can be used both to monitor conditions and to control machinery, the IoT has broad implications for safety, with respect to both improvements and risks. For example, objects embedded in pipelines can monitor both the condition of the equipment and the flow of contents. Among other benefits, that can help both to expedite shutoffs in the event of leaks and to prevent them through predictive maintenance.
Connected vehicles can help reduce vehicle collisions through crash avoidance technologies and other applications.110 Wireless medical devices can improve patient safety by permitting remote monitoring and facilitating adjustments in care.
However, given the complexities involved in some applications of IoT, malfunctions might in some instances result in catastrophic system failures, creating significant safety risks, such as flooding from dams or levees. In addition, hackers could potentially cause malfunctions of devices such as insulin pumps or automobiles, potentially creating significant safety risks.
